Patent DE-3338237-A1 (DE)
Title: Device for evaporating and heating liquefied natural gas
Inventor: KOENIG WOLFRAM DIPL ING
IPC: F02B63/04
Filed: 1983-10-21
Abstract: In the evaporation of liquefied natural gas, there are applications in which the supply of energy by means of steam, electricity or combustion is not possible or not permissible, e.g. in the explosion range or in offshore operation. In these cases, use is made of the waste heat of an internal combustion engine to evaporate the natural gas. The internal combustion engine is present in any case, and drives the feed pumps, for example. Since the pressure and the delivery rate fluctuate, there is also a variation in the waste heat of the internal combustion engine and thus in the evaporation capacity. An electricity generator (11), to which a plurality of connectable electric heating elements (14), which are arranged in a heat exchanger (13) through which cooling water flows, are connected, is coupled to the internal combustion engine (7) in order to compensate these fluctuations. A uniform evaporation energy can be generated by connecting the heating elements. This can be backed up if necessary by varying the generator speed. <IMAGE>

Title: Method and circuit for suppressing error signals in scanners of physical quantities, particularly in thread tension scanners of open-end spinning machines
Inventor: SLOUPENSKY JIRI DIPL ING
IPC: D01H13/16
Filed: 1984-02-29
Abstract: The subject-matter of the invention is a method and a circuit for suppressing the sensitivity of the scanners of mechanical quantities on textile machines to wild, arbitrary signals. The invention is suitable for use on high-performance textile machines, particularly open-end spinning machines and makes it possible to eliminate the unwanted influence of machine vibrations. Such vibrations act on highly sensitive sensors monitoring the drop of thread tension - that is to say thread breakage - particularly during the spinning-out of fine yarn types. The influence of wild signals is reliably eliminated by comparing a signal from the thread tension sensor with a test signal of adjustable frequency and by using a pulse counter with adjustable capacity. <IMAGE>

Title: Endoprosthesis anchorage
Inventor: BLAUTH WALTER PROF DR
IPC: A61F2/38
Filed: 1984-03-13
Abstract: The invention relates to an endoprosthesis anchorage for total prostheses of the knee, comprising a femoral and a tibial part and intended for cementless, intramedullary stem implantation. Annular circumferential projections are provided at regular intervals on the cylindrical stem core, the projections having a trapezoidal shape in lateral section. The surface surrounding the outer points of these projections forms a cone which has its maximum diameter at the location of the tibial bearing surface or the condyles of the femur. The diameter of the ring nearest to the stem tip projects only a few mm above the level of the stem core. The terminal section of the stem is smooth, while its tip is clearly rounded. The annular projections join the stem core with a blunt angle, taper off toward the tip to their maximum radius distance and rise again at the bottom side toward the stem. Longitudinal grooves reaching down to the stem core interrupt the projections.

Title: Sheet feeder for sheet processing machines
Inventor: ZIMMERMANN HANS
IPC: B65H29/04
Filed: 1984-03-14
Abstract: The invention relates to a sheet feeder for sheet processing machines in which the chain and the gripper carriages are guided separately and in which the chain path deviates from the gripper carriage path to slow down deposition of sheets in the deposition region. The gripper carriages are articulated with the chain by means of connecting rods. The object of devising a sheet feeder for printing presses, in which fluctuations in the driving torque due to deceleration of the gripper carriage in the sheet depositing region and its subsequent reacceleration are reduced to a very substantial extent and the wear-promoting dynamic additional forces arising from this are minimised, is achieved by assigning a stationary parabolic upper and lower supporting element to the chain deflecting wheel in the inlet and outlet region of the chain and by arranging in the deflection and outlet region of the gripper carriage a first curved section which is helical in shape and ascends steeply, a second curved section which is helical in shape and ascends more gently as a transition section and an outlet section which ascends at a greater exponential rate <IMAGE>

Title: Simultaneous SO2 and NOx removal by employing an electrolytic process while taking account of the conductivity of the scrubbing solution
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1985-12-24
Abstract: The main application P 3447425.0 describes a process for SO2 and NOx removal by using an electrolytic process. In order to be able to operate such a process economically, it is proposed according to the invention to employ a scrubbing liquid in the process, based on complexed iron(II) solution, whose conductivity is maintained between 70 and 100 mS/cm. In order to obtain this conductivity it is further proposed that the scrubbing liquid be set to a pH between 4.5 and 6.5. In addition, the scrubbing liquid is enriched with an Fe concentration of 5-6.5 g/l, the Fe(II) content, for a scrubbing efficiency above 90%, expediently being greater than 2 g/l scrubbing solution and, for a scrubbing efficiency of approximately 80% at less than 2 g/l scrubbing solution, the overall content of Fe(II) and Fe(III) being kept at 5-6.5 g/l. It was further found that a significant improvement of the conductivity can be achieved by employing carboxylic acids.
